Carbon Dioxide
Carbon Dioxide, CO2, is a tasteless, colorless, odorless, nonflammable gas with an acidic taste that is a molecule formed from one carbon atom and two oxygen atoms.
Carbon dioxide is an important part of the basic life cycle in nature. It is released by plants and exhaled by humans and animals, then used by plants in photosynthesis. Plants, in turn, release oxygen, which humans and animals require.
Atmospheric air contains only 0.03% of Carbon Dioxide, so it is not a commercially feasible source; rather, numerous manufacturing processes furnish by-product streams from which carbon dioxide may be obtained, such as the combustion of coal and natural gas.
Carbon Dioxide's solid phase is Dry Ice.
Carbon Dioxide is used to carbonate soft drinks , as a shielding gas in the arc welding process, as a lasing gas in lasers, fire extinguishers, paint ball propellant and more.
